I just opened up this machine for the 2nd time in two days to put back the original DVD drive, because I didn't check that the replacement worked before inserting it 
While I had it open, I wondered how many people would be able to tell what model this is?
Once the question has been answered correctly, post your own open Apple machines and see how long it takes for them to be properly identified.
One at a time please so we can know which is current
I anticipate this will get more and more difficult so that's why I've started with a relatively easy machine.
Enjoy
Cheers
Hugh
